“DEPENDENCE OF THE BOND WORK INDEX ON THE FILLING RATIO AND TEST SIEVE APERTURE”. [PDF]
JES. Journal of Engineering Sciences, 2020 Knowledge of the grindability behavior of solid materials can be considered as an important factor for the design of their grindability systems. Bond work index (Wi) can be considered as one of the most important affecting factors in the design of grinding systems which express on the value of energy (kwh) consumed per ton of the ground ore.
